Lead-free piezoceramics
Yasuyoshi Saito,Hisaaki Takao,Toshihiko Tani,Tatsuhiko Nonoyama,Kazumasa Takatori,Takahiko Homma,Toshiatsu Nagaya,Masaya Nakamura +7 more
TL;DR: A lead-free piezoelectric ceramic with an electric-field-induced strain comparable to typical actuator-grade PZT is reported, achieved through the combination of the discovery of a morphotropic phase boundary in an alkaline niobate-based perovskite solid solution, and the development of a processing route leading to highly textured polycrystals.

TL;DR: In this paper, the authors proposed a piezoelectric ceramic composition which is lead-free and has high dielectric characteristics, and is excellent in, especially, at least one of a piezo-lectric charge constant d 31, a relative permittivity, a Dielectric loss, and a Curie temperature Tc.

Tatsuhiko Nonoyama,Toshiatsu Nagaya,Yasuyoshi Saito,Kazumasa Takatori,Hisaaki Takao,Takahiko Homma +5 more
TL;DR: A piezoelectric ceramic composition not containing lead, able to be sintered at ordinary pressure, and superior to the past in at least one of the properties unique to the traditional lead-lead-lead mixture, such as the d 31 constant, is defined in this article.

Crystal oriented ceramics and production method of same
Tatsuhiko Nonoyama,Toshiatsu Nagaya,Hisaaki Takao,Takahiko Homma,Yasuyoshi Saito,Kazumasa Takatori,Masaya Nakamura +6 more
TL;DR: In this paper, the authors presented a crystal oriented ceramics, which are composed of a polycrystalline substance of an isotropic perovskite compound represented by the general formula: {Li x (K 1-y Na y ) 1-x }{Nb 1-z-w Ta z Sb w }O 3 (wherein, 0 ≤ x ≤ 0.2, y ≤ 1, x + z + w > 0).
Patent
Grain oriented ceramics and production method thereof
Hisaaki Takao,Takahiko Homma,Yasuyoshi Saito,Kazumasa Takatori,Tatsuhiko Nonoyama,Toshiatsu Nagaya,Masaya Nakamura +6 more
TL;DR: In this paper, a grain oriented perovskite-type compound is represented by formula (1): {Lix(K1−yNay)1−x}(Nb1−z−wTazSbw)O3 in which x, y, z and w are in respective composition ranges of 0.0001 to 0.15 mol of any one or more additional element selected from metal elements, semimetal elements, transition metal elements and noble metal elements belonging to Groups 2 to 15 of the Periodic Table.
